Did you get your issue resolved ?
I'm assuming the standard links provided didn't help.
My iphone id stuck with the picture of a usb cable connecting to the itunes icon.
I have tried any combination of holding the home button and/or the sleep button for 10, 20 , 30 , 40 60 sec.
But it's still stuck
Your phone is in recovery mode and needs to be restored. If iTunes is not detecting it, try going through the troubleshooting steps in item #5 at the bottom of this article: http://support.apple.com/kb/TS1538, under "If the device is not recognized while in Recovery Mode".
